West Ham made an emphatic start to the new season when they convincingly beat title hopefuls Arsenal 2-0 at the Emirates on Sunday.

Many pundits had criticised Hammers co-owners David Sullivan and David Gold for parting company with Sam Allardyce in the summer saying the club should simply be happy to survive in the top flight.

But while it is still very early days, many have been forced to reassess their predictions for the east Londoners this season after the powerful display against the Gunners.

And now speaking to West Ham's official website, cult hero 'keeper Adrian has warned rival clubs there is more where the Arsenal performance came from and it is all down to a change of approach by new boss Bilic.

"Slaven wants us to play more with the ball from the keeper and the defence and keep the possession.

"We are attacking a lot which is dangerous for the other teams."

Tough talking will be tested

Adrian's tough taking will be put to the test this weekend when West Ham, who have a tradition of beating the so-called bigger sides before losing against supposedly inferior opposition, take on Leciester City at Upton Park.

As the home side against a lesser team, West Ham will be expected to go on and make it two wins out of two.

While Adrian admits every game in the Premier League is tough – particularly with Leicester coming off the back of a 4-2 opening weekend win over Sunderland – he is confident Bilic has the answers to keep the Hammers focused.

“We now play our first game at home in front of our own fans and you never have an easy game in the Premier League but we will be doing everything to get the three points," Adrian added.

A dig at 'negative' Allardyce?

The Spaniard's words could be seen as a slight dig at Bilic's predecessor Sam Allardyce, who was the man that brought the former Real Betis stopper to the Irons.

It was Allardyce's pragmatic approach to matches, especially in 2015, which ultimately cost him his job as West Ham fans grew tired of what they saw as a negative appraoch to matches, particularly away from home.

At Arsenal Bilic played two strikers and star signing Dimitri Payet in behind with a high-pressing and counter attacking style suffocating Arsenal.
